Season the chicken breasts with salt and pepper.
In a large skillet, heat olive oil over medium heat. Add the chicken and cook for 6-7 minutes on each side, or until cooked through. Remove from the skillet and let rest before slicing.
While the chicken is resting, cook the fettuccine according to package instructions. Drain and set aside.
In the same skillet, add minced garlic and sauté for about 1 minute until fragrant.
Pour in the heavy cream and bring to a simmer. Stir in the Parmesan cheese and nutmeg, mixing until smooth.
Add the cooked fettuccine and sliced chicken to the sauce, tossing to coat.
For the garlic bread, preheat the oven to 375°F.
In a small bowl, mix the softened butter, minced garlic, salt, pepper, and dried parsley.
Slice the baguette in half lengthwise and spread the garlic butter mixture evenly on both halves.
Place on a baking sheet and bake for 10-12 minutes, or until golden and crispy.
Serve the Chicken Alfredo topped with chopped parsley, alongside the garlic bread.
